Looking for a TDT PA5 attenuater with USB

Hello,

Has anyone got one of the old Tucker Davies PA5 attenuators that connects via USB that they are willing to sell? The newer fiber optic ones are not compatible with out system.

Thanks

Subject: [AUDITORY] calibration of insert earphones

Hello,

I am researching the equipment necessary to properly measure the level of signals reproduced through insert earphones.

I suspect the best way is to use one of these babies:

Can anyone please give me a rough estimate of the cost of a B&K artificial ear?

Are there cheaper ways to measure earphone levels that don't contemplate buying equipment delivered with a mahogany case (e.g., building a home-made coupler for the level meter)?!? For my applications a level-measurement error of, say, ± 3 dB might be acceptable.

Cheers,

Bruno
